To aZZ whom it may concern,.-

Be it known that l, ROBERT MILLER, a citizen of the United States, residing at Redfield, in the county oi Spink and State of South Dakota, have invented a new and useful HotlVater Heater, ot which the following is a specification.

This invention relates to heaters forwarming apartments, dwellings, offices, public buildings, and other places where hot water can be economically used for heating purposes.

The object ot the improvement is to combine with a stove of ordinary construction, whether base or surface burner, cook or heating stove, Ameans for heating water which may be conveyed. to a distant point for utilization or made available for heating the same room in which the stove is located.

The invention consists in combining with a stove a magazine having an annular chamber forming a water-space, a hollow lire-pot to receive a supply of water to be heated, and a connecting pipe or coil, the latter being inclosed within the walls or casing of the stove to be concealed and receive the full beneiit of the heat and provide in effect a continuation of the magazine, and establishing communication between the water-spaces of the magazine and the iire-pot.

For a full understanding of the merits and advantages of the invention reference is to be had to the accompanying drawings and the following description.

The improvement is susceptible of various changes in the form, proportion, and the minor details of construction without departing from the principle or sacrificing any of the advantages thereof, and to a full disclosure of the invention an adaptation thereof is shown in the accompanying drawings, in which Figure l is a vertical central section of a magazine heatingstove having the invention applied, the lower portion being broken away. Fig. 2 is a sectional detail on the line X X of Fig. l, parts being omitted. Fig. 3 is a horizontal section of the magazine on the linc Y Y of Fig. l..

Like parts are designated in the drawings and referred to in the subjoined description by the same reference characters.

The stove illustrated is of the common type generally employed for heating purposes, and is shown to illustrate the application of the invention. The magazine l is iitted to the open end of the stove 2 in the usual manner, and is closed by the cap 3. A shell a encircles the lower contracted portion ofthe magazine and forms therewith a water-space 5, and bosses G and 7 are formed with the shell l and are threaded in the usual way for the coupling thereto of the pipes S and 9. Byhaving the water-space 5 located at the lower end ot' the magazine it is in proximate relation to the lire-pot and prevents the burning oi' the lower portion of the magazine, which is the chief source of expense in repairing stoves of this character. Moreover, the heat from the lire and the waste products of combustion is utilized to the best possible advantage for maintaining the water at a proper temperature to effect the desired end.

The fire-pot lO is hollow to provide a waterspace ll, and has a threaded boss .l2 for the coupling thereto of the pipe S, which latter may be of any forma-tion, but preferably consists of a coil which is disposed in vertical relation and incloses the water-space 5 in its upper portion, the lower portion extending from the magazine to the lire-pot and forming practically a continuation. of the said magazine to prevent the spreading of the coals and the engagement of the said coals with the walls or casing of the stove. A reservoir or tank i3 is arranged adjacent to the stove and has connection with the waterspace 5 of the magazine by means of the pipe 0, and with the water-space ll of the rire-pot by means of a pipe li, the latter having a valve l5 to cut off or regulate the iiow of water to the water-space ll. The pipe 9 is supplied with a valve 16 to shut off communication between the reservoir 13 and the water-space 5 when it is required to replenish the said reservoir i3, or for any required purpose. A safety-valve l? is provided and connected with the reservoir i3 to relieve any abnormal pressure from within in the event of the pressure of steam exceeding a point of safety.

The reservoir or tank i3, in addition to containing a supply oil water to keep the waterspaces 5 and ll and the coil S full, acts in the capacity oi' a radiator to warm the air in the IOO room in which it and the Stove are located. For heating a distant room or apartment one or more radiators will be looped into the pipe 14 in the usual way of setting hot-water heating apparatus, so that the circulation of the water may be established through the radiators, the water-spaces 5 and 1l, and the pipes 8, 9, and 14. To secure the best results the parts are disposed within the stove substantially as shown, and the connecting-pipe 8 takes the form of a coil. The pipes 9 and 14 extend through suitable openings in the side of the stove, a close iit being had to obviate the escape of coal gas and dust into the room. The inner wall of the fire-pot l0 swells or bulges to secure a maximum amount of heating-surface and to reduce the lower portion of the fire-space so as to conform to the outline of the bed of coals commonly assumed by the latter after the fire has been burning for a considerable time.

Having thus described the invention, what is claimed as new isl. In a hot-water heater, the combination of a magazine having a water-space at its lower end, a hollow iire-pot forming a waterspace and arranged a distance below the water-space of the magazine, and a coil of pipe encircling the water-space of the magazine and having direct connection therewith at its upper end, and extending across the space formed between the magazine and repot and having direct connection at its lower end with the water-space of the fire-pot, sub'- stantially as shown for the purpose described.

2. In a hot-water heater, the combination of an inelosed magazine and fire-pot disposed in vertical relation and spaced apart, the firepot being hollow to provide a water-space and the magazine having a water-space at its lower end, a coil of pipe extending across the space formed between the magazine and iire-pot and having its lower end in direct communication with the water-space of the fire-pot, and having its upper portion encircling the water-space of the magazine and in direct communication with the upper portion thereof,a reservoir exterior to the heater, and independent connections between the reservoir and the water-spaces of the magazine d and fire-pot, substantially as shown and for the purpose described.

3. The combination with a stove, of a magazine having a surrounding shell at its lower end forming a water-space, a hollow fire-pothaving its inner wall bulging inward and inclosing a water-space, a coil of pipe encircling the water-space of the magazine and eX- tending across the space formed between the magazine and lire-pot, and connecting the outer shell of the magazine with the inner wall of the fire-pot, and a reservoir or tank exterior to the stove and having connection, respectively, with the water-spaces of the magazine and nre-pot, and having a safetyvalve and means for controlling and shutting off communication between the reservoir and the water-spaces of the magazine and iire-pot. substantially as described.

In testimony that I claim the foregoing as
